Excavator control method, excavator control device, and excavator
The invention provides a control method and device of an excavator and the excavator. The control method of the excavator comprises the steps that at least one of the pilot pressure of a bucket rod, rotation priority current and the pressure difference of a rod cavity of the bucket rod is obtained; according to a first mapping relation between a first parameter and a current value and the first parameter, a first input current is calculated, the input current of a first proportional flow valve is adjusted to the first input current, and the first parameter is at least one of bucket rod pilot pressure, rotation priority current and pressure difference. The method solves the problem that a traditional excavator valve-controlled hydraulic system adopts one valve element to control an inlet oil way and an outlet oil way at the same time, and consequently the efficiency of the hydraulic system is low.
本申请提供了一种挖掘机的控制方法、挖掘机的控制装置以及挖掘机，挖掘机的控制方法包括：获取斗杆先导压力、回转优先电流以及斗杆的有杆腔的压力差中的至少一个；根据第一参数和电流值的第一映射关系和第一参数，计算第一输入电流，并将第一比例流量阀的输入电流调整至第一输入电流，其中，第一参数为斗杆先导压力、回转优先电流以及压力差中的至少一个。该方法解决了传统的挖掘机阀控液压系统采用一根阀芯同时控制进出口油路的方式，造成液压系统效率低的问题。
